Rapid Dopaminergic Signatures in Movement: Reach Vigor Reflects Reward Prediction Error and Learned Expectation

This study shows that movement vigor tracks reward prediction error and reward expectation, linking dopaminergic signals to motor control across multiple time scales.

The vigor paradox: saccade velocity during deliberation encodes utility of effortful actions

The paper shows that saccade velocity during deliberation reflects the subjective value of effortful choices, even when the movement itself does not influence the decision.
